Maintaining healthy levels of vitamin D is essential in all stages of life for immune system and bone health. The current recommended daily vitamin D intake of 400 IUs is based on the minimum allowance to protect against bone disease. However, an upward revision of the FDA’s guideline is now under consideration in light of new research, especially pertaining to immune function. Although direct sunlight exposure is a good source of vitamin D, most individuals don’t get enough sun due to seasonal changes, latitude, lifestyle and daily bathing and showering (soap washes the vitamin D precursors from the skin surface before the 48 hours required for complete absorbtion). Therefore vitamin D supplementation can be of great benefit for improving immune system functionality. Vitamin D deficiency is common, particularly among the elderly and most individuals can greatly benefit from regular supplementation.
